The Bank of England has maintained interest rates at 3.75%, with supply-side factors complicating the assessment of appropriate monetary policy. Inflation driven by supply constraints requires different responses than demand-driven inflation.
The monetary policy committee’s 5-4 vote reflected debate about whether current inflation primarily reflects excess demand that monetary policy can address, or supply constraints that rate changes can’t fix. The painful price surge following pandemic disruptions and the Ukraine invasion was largely supply-driven, making traditional monetary policy less effective.
Interest rate changes primarily affect demand by making borrowing more or less expensive. If inflation stems from supply problems—broken supply chains, energy shortages, labor scarcity—then raising rates to crush demand can cause unnecessary economic damage without addressing root causes. This was partly the challenge in recent years.
However, sustained inflation can generate demand-side pressures even when initially supply-driven. If workers demand higher wages to compensate for price increases, and businesses can pass these costs to customers, inflation becomes self-perpetuating through demand channels. The Bank must judge whether this dynamic is occurring.
Governor Andrew Bailey’s projection that inflation will fall to around 2% by spring suggests supply-side pressures are easing naturally, allowing demand-side factors to become more important. The GDP forecast of 0.9% and unemployment rising to 5.3% indicate demand is already weak. Chancellor Rachel Reeves’s budget measures, including utility bill cuts and rail fare freezes from April, address supply-side costs directly through policy rather than relying only on monetary demand management. The forecast inflation of 2.1% by mid-2026 reflects both easing supply constraints and appropriate demand calibration through interest rates.
